Varnish Cache Support

Increase the performance of your server with Varnish

Varnish Cache offers drastic performance benefits for dynamic, high-traffic websites

If you have a content-heavy website which often gets traffic spikes, then Varnish can be the right solution for you. It will help you to serve thousands of simultaneous requests without overloading the server and your database.


Configuring Varnish to serve content properly and following your organizations requirements can be tricky. Cache expiry rules, time to live, URL caching, and object caching requirements in Varnish are highly complex. Leverage our extensive experience building, maintaining, and configuring Varnish, so it does exactly what you want it to do and nothing more.

How we can help:

  • Varnish cache installation
  • Bespoke Varnish .vcl configuration file
  • Troubleshooting caching problems
  • Setting up Varnish in high availability mode
  • Architecture of private CDN solutions using Varnish clustering and load balancing

Why Use Varnish?

Drastically reduces server loads

The biggest reason to use Varnish is so you can serve thousands of concurrent requests per second without overloading your web server and database server. Because Varnish can serve cached content directly from primary memory, there is no disk i/o operation to slow things down. No database calls are made, and there is absolutely no processing involved. Results are that response times and the server resource usage are always kept at a bare minimum.

Varnish is highly customizable

In the right hands VCL is very powerful and allows you to modify nearly every aspect of HTTP request and response. Our engineers can help you customize Varnish as per your requirements. We play with the Varnish Configuration Language (VCL) file - to fine tune your performance and tell Varnish exactly how to handle the caching process including when and what to cache, when not to cache, and how long to keep the cached content in memory.

Increased resilience with High Availability

If your application or website is mission critical - high availability can further improve overall performance as well as increase resilience to hardware failure. We have deep experience in turning pairs of Varnish Cache servers into "highly available" caching clusters. This not only removes a single-point-of-failure, but can help reduce cache misses even further!

FAQ

  • How do I receive support for Varnish Caching? Varnish support is available on the enhanced and enterprise support plans. Very complex Varnish configurations may require an additional professional services engagement.
  • Is Varnish right for me? Varnish Caching isn't for everyone. If you're interested in implementing Varnish Cache but are not sure if it is worth the effort, contact our performance engineers for a no obligation consultation.
  • Can I use Varnish with cPanel and Plesk? There are certain things that control panels are still having difficulties playing friendly with. And that's native NGiNX webserver, and Varnish Cache. While there are plugins that claim to offer a start/stop Varnish experience with cPanel, they are still BETA at best.
